1 - Node Configuration Reference

This page provides a comprehensive reference of all node configuration options recommended for the Indiana Hoosier Mesh network.

LoRa Settings

Channel Settings

Security Settings

*Note: Unique to each node

User Configuration

Important: Meshtastic allows encrypted transmissions. However, US Amateur Radio licensing prohibits encryption. See FCC guidelines and our Amateur Radio & Meshtastic guide for complete details.

Device Settings

Device Role Notes

• CLIENT (default): Standard mesh participant
• CLIENT_BASE: Use for roof/attic-based nodes. Don’t forget to favorite your local owned nodes
• ROUTER / ROUTER_LATE: Avoid unless on a very tall tower. Check with experienced RF operators on the Indiana Mesh Discord before using these roles

Serial Settings (Optional)

2 - Advanced Configuration - MQTT & Telemetry

This page covers advanced configuration options for MQTT (internet connectivity), Serial interfaces, and Telemetry collection.

MQTT (Optional but Recommended)

MQTT allows you to access and control your Meshtastic nodes over the internet, integrating them with other services and creating mesh monitors.

MQTT Configuration

Important MQTT Considerations

Best Practices:

• Use MeshMap.net to check specific root topics of users in your area before enabling MQTT
• Consider the impact on your device’s performance and battery life
• Start with MQTT disabled and enable only when needed
• Monitor your device’s resource usage after enabling MQTT

Finding Your Root Topic

Check MeshMap.net to see what root topics other users in your region are publishing to. This will help you understand the network topology and choose an appropriate topic for your node.

Telemetry (Optional)

Telemetry allows your node to collect and broadcast device metrics like temperature, humidity, battery status, and GPS location.

When to Enable Telemetry

• Enabled by default on devices with environmental sensors
• Useful for nodes you want to monitor remotely via MQTT
• Increases power consumption on battery-powered devices
• Consider your use case before enabling

Serial/USB Configuration (Optional)

The Serial interface allows you to communicate with your Meshtastic device via USB or serial connection for advanced debugging and integration with external systems.

Use Cases

• Debug and monitor device behavior via serial port
• Integrate with external applications or sensors
• Advanced troubleshooting of device issues
• Integration with automations or home assistant systems

External Notifications (Optional)

Configure how your device alerts you to incoming messages.

These settings allow you to customize notification behavior based on message type and your preferences.
